* [svn-r764] Changes since 19981014Robb Matzke1998-10-161-3/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./bin/trace ./src/H5.c ./src/H5F.c ./src/H5Fprivate.h ./src/H5Fpublic.h Added a `scope' argument to H5Fflush() which should be either H5F_SCOPE_LOCAL or H5F_SCOPE_GLOBAL and determines which files are flushed (just the specified file or the entire virtual file). ./src/H5F.c Added reference counts to the H5F_t struct so we get the correct behavior between H5Funmount() and H5Fclose(). ./src/H5O.c Fixed a memory leak that happens during error handling. ./test/cmpd_dset.c ./test/unlink.c Fixed a memory leak. ./test/mount.c Enabled the H5Fclose() test.
* [svn-r761] Changes since 19981013Robb Matzke1998-10-141-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5.c Fixed a signed vs. unsigned comparison. ./src/H5D.c Setting a fill value of all zeros will cause the fill value to be written to the dataset instead of relying on the low-level file driver initializing unwritten areas with zero. ./src/H5D.c ./src/H5F.c ./src/H5Fprivate.h ./src/H5G.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5O.c ./src/H5T.c More file mounting stuff. ./src/H5I.c Fixed a bug where trying to close an invalid object id caused a core dump. For instance, H5Gclose(-1). ./MANIFEST ./test/Makefile.in ./test/mount.c [NEW] Mounting tests. ./src/H5R.c Fixed a couple (herr_t)NULL casts.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./doc/html/H5.format.html ./src/H5HG.c Fixed a bug in the global heap that caused H5HG_read() to write past the end of the buffer in certain cases. ./test/big.c The test is skipped if hdf5 was configured with `--disable-hsizet'. ./src/H5Ofill.c Data type conversions are implemented for the fill value. ./src/H5.c Tracing prints one of H5P_FILE_CREATE, H5P_FILE_ACCESS, H5P_DATASET_CREATE, H5P_DATASET_XFER, or H5P_MOUNT instead of the more cryptic H5I_TEMPLATE_* constants. ./src/H5D.c Removed prototype for H5D_find_name(). ./src/H5I.c The GROUP_MASK and ID_MASK are both calculated from GROUP_BITS instead of being set by hand. We don't use the sign bit of hid_t; all valid hid_t values are positive so we can say things like `if ((file=H5Fopen(...))<0)'. Changed `(int)pow(2.0,x)' to `1<<x' so we don't have to worry about rounding. Fixed H5I_get_type() so it doesn't always fail an assertion. ./src/H5E.c ./src/H5Epublic.h Added minor error H5E_MOUNT ./src/H5F.c ./src/H5Fprivate.h Added H5Fmount() and H5Funmount(). Mounting and unmounting works as documented but some of the other things aren't implemented yet, the biggest being current working groups always acting on the root of the mount tree, and H5Fclose() closing the entire tree. The rest of the stuff will be added shortly... ./src/H5P.c ./src/H5Ppublic.h Added the H5P_MOUNT property list but haven't implemented any particular properties for it yet. ./src/H5Gstab.c Hard links across files return an error instead of failing an assertion.
* [svn-r734] Changes since 19981001Robb Matzke1998-10-021-1/+2
| | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c ./src/H5Fistore.c ./src/H5Fprivate.h Fixed a couple things for parallel hdf5 that I broke with the last checkin. ./src/H5Ofill.c If no fill value is specified it isn't added to the object header. ./tools/h5ls.c Added a line-feed after `Unknown object' is printed. ./tools/h5tools.c Fixed printing of scalar values. Need to still track down a failed assertion when H5Sselect_hyperslab() is called with a zero size....

Added a few missing files. Are all of these supposed to be distributed? ./tools/testfiles/h5dumptst.c + ./tools/testfiles/tall-1.ddl + ./tools/testfiles/tall-2.ddl + ./tools/testfiles/tall-3.ddl ./tools/testfiles/tall.ddl ./tools/testfiles/tall.h5 + ./tools/testfiles/tattr-1.ddl + ./tools/testfiles/tattr-2.ddl + ./tools/testfiles/tattr-3.ddl + ./tools/testfiles/tattr-4.ddl ./tools/testfiles/tattr.ddl ./tools/testfiles/tattr.h5 + ./tools/testfiles/tdset-1.ddl + ./tools/testfiles/tdset-2.ddl + ./tools/testfiles/tdset-3.ddl + ./tools/testfiles/tdset-4.ddl ./tools/testfiles/tdset.ddl ./tools/testfiles/tdset.h5 + ./tools/testfiles/tgroup-1.ddl + ./tools/testfiles/tgroup-2.ddl + ./tools/testfiles/tgroup-3.ddl ./tools/testfiles/tgroup.ddl ./tools/testfiles/tgroup.h5 + ./tools/testfiles/tslink-1.ddl + ./tools/testfiles/tslink-2.ddl ./tools/testfiles/tslink.ddl ./tools/testfiles/tslink.h5 ./src/H5B.c ./src/H5Bprivate.h ./src/H5D.c ./src/H5Dprivate.h ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5Gstab.c ./src/H5P.c ./src/H5Ppublic.h ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Spoint.c ./src/H5Sprivate.h ./test/istore.c Implemented split ratios as documented in previous e-mails. Frank, the new API functions are H5Pget_btree_ratios() and H5Pset_btree_ratios(). ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Spoint.c ./src/H5Sprivate.h Added more type checking for the data transfer property list passed to these functions. ./src/H5D.c Added a dataset transfer property list as an argument to H5D_allocate() for the parallel version in order to pass split ratios down to H5F_istore_lock(). Eventually we won't need the split ratios for H5D_allocate() because we'll build a completely full B-tree from the leaves up, but it might be useful to have other transfer properties at that level anyway. I always caled H5D_allocate() with &H5D_dflt_xfer. ./MANIFEST ./test/Makefile.in ./test/overhead.c [NEW] Added an `overhead' test run by `make timings'.
* [svn-r726] Changes since 19980924Robb Matzke1998-09-281-1/+1

* [svn-r720] Changes since 19980922Robb Matzke1998-09-241-4/+5

The default number of slots is 521 and the default maximum size is 1MB. ./src/H5Fistore.c ./src/H5Fprivate.h Finished optimizations. The cache is now a hash and a linked list instead of an array. The cpu time on my machine for H5F_istore_lock() has been cut by 60% and H5F_istore_unlock() by 35%.
* [svn-r714] Changes since 19980911Robb Matzke1998-09-221-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- This checkin is to fix a couple bugs for Jim Reus. Some features are not fully implemented but it shouldn't break anything. ./config/conclude.in ./test/Makefile.in `make clean' removes object files from the test directory as well as a couple more *.h5 temp files. ./config/hpux9.03 [NEW] New config file for HP/UX 9.03 ./src/H5B.c ./src/H5Bprivate.h ./src/H5Fistore.c ./src/H5G.c ./src/H5Gnode.c ./src/H5Gpkg.h ./src/H5Gprivate.h ./src/H5Gstab.c Not-yet-complete version of object removal. ./src/H5Fistore.c ./src/H5Fprivate.h Experimental optimizations, disabled by default. ./src/H5Fprivate.h Default low-level driver was changed to H5F_LOW_SEC instead of H5F_LOW_STDIO because the sec2 driver is much easier to debug. ./src/H5Fsplit.c ./src/H5G.c ./src/H5Z.c Changed a couple return statements to HRETURN. ./src/H5Odtype.c Removed a check for nested compound data types from back when they weren't implemented that raised an error. ./tools/h5tools.c Increased temp buffer sizes and added a check for buffer overflow so we fail an assertion (hopefully). This really needs to be fixed sometime. Added support for printing H5T_STRING data types.

* [svn-r630] Added code to eliminate redundant writes of metadata,Robert Kim Yates1998-08-281-0/+2
| | | | | | so only proc 0 writes it to disk. The elimination is activated only when the environment variable HDF5_MPI_1_METAWRITE is nonzero; otherwise all processes that opened the file will write the metadata to disk.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./bin/release Added ./Makefile to the distribution again -- it got lost in the changes last week although it isn't all that important a file since it gets clobbered by configure anyway. ./bin/trace ./doc/html/Filters.html ./doc/html/H5.format.html ./doc/html/H5.user.html ./src/H5.c ./src/H5D.c ./src/H5Dprivate.h ./src/H5E.c ./src/H5Epublic.h ./src/H5Farray.c ./src/H5Fistore.c ./src/H5Fprivate.h ./src/H5O.c ./src/H5Ocomp.c ./src/H5Oprivate.h ./src/H5P.c ./src/H5Ppublic.h ./src/H5Sall.c ./src/H5Shyper.c ./src/H5Spoint.c ./src/H5Sprivate.h ./src/H5Ssimp.c ./src/H5Z.c ./src/H5Zprivate.h ./src/H5Zpublic.h ./src/hdf5.h ./test/dsets.c ./tools/h5ls.c Added the data filter pipeline, a generalization of the compression stuff which allows things like checksums, encryption, compression, performance monitoring, etc. See ./doc/html/Filters.html for details -- it replaces the Compression.html doc. ./src/H5T.c Cleaned up debugging output. ./config/linux Added checks for egcs and pgcc and changed optimization flags for the compilers. ./src/H5G.c ./tools/h5dump.c Fixed compiler warnings in these files and others. ./configure.in ./src/H5private.h ./test/mtime.c Added a check for difftime() and defined HDdifftime() to do something else on systems that don't have difftime().
* [svn-r511] Changes since 19980715Robb Matzke1998-07-151-2/+2
| | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5Flow.c ./src/H5Fprivate.h ./src/H5Fsplit.c Changed the allocation size request from `size_t' to `hsize_t' because it was overflowing for the `big' test. ./src/H5detect.c If `long double' and `double' are the same size then we define H5T_NATIVE_LDOUBLE to be the same as H5T_NATIVE_DOUBLE. Similarly for `long' vs. `long long' and `unsigned long' vs. `unsigned long long'. ./test/Makefile.in Added `big' to the list of tests to normally run. ./test/big.c Added a check to see if the file system supports holes and if it doesn't then the test is skipped.
* [svn-r477] Changed the way file-space allocation for the data part of a dataset.Albert Cheng1998-07-091-8/+2
| | | | | | | | | | | | | | | | | H5D.c: Created a new function H5D_allocation to do allocation of all datasets. According to the storage layout, it calls the appropriate function. H5Fprivate.h: H5Fistore.c: H5F_istore_allocation now takes a dimension array, (old version used a space pointer) to determine how many chunks to allocate. Changed H5F_istore_get_addr to a private (static) function. No one outside of H5Fistore.c is calling it. Removed three forward declarations now that they are not needed. Tested platform: O2K
* [svn-r473] Changes since 19980708Robb Matzke1998-07-081-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5Fistore.c ./src/H5S.c Fixed places where `herr_t' functions returned NULL for failure: H5F_istore_get_addr() and printf(?!?) (probably because a printf() was in the first column :-/ so I don't know what function it really was that I fixed), and H5S_extent_copy(). ./src/H5Fprivate.h Added declarations for H5F_istore_get_addr() and H5F_istore_allocate(). ./src/H5S.c ./src/H5Sprivate.h Split H5Sset_extent_simple() into H5S_set_extent_simple() and replaced calls to the API function with calls to the internal function. Changed calls to H5Screate() to H5S_create() and H5Sclose() to H5S_close(). ./src/H5Shyper.c ./src/H5Spoint.c Removed unused labels and variable. ./src/H5T.c ./src/H5Tconv.c Changed calls to H5Tfind() to H5T_find(). ./src/H5TB.c Split function return type onto a separate line for five functions and added API tracing calls.
* [svn-r418] ./html/Files.htmlRobb Matzke1998-06-101-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ./src/H5F.c ./src/HFcore.c ./src/H5Ffamily.c ./src/H5Flow.c ./src/H5Fmpio.c ./src/H5Fprivate.h ./src/H5Fsec2.c ./src/H5Fsplit.c ./src/H5Fstdio.c ./src/H5MF.c ./src/H5P.c ./src/H5Ppublic.h Added H5Pset_alignment() so that it is now possible to align file allocation requests on application-specified boundaries. Any request >= the specified threshold will begin on an address which is a multiple of the specified alignment. Defaults are one for threshold and alignment. The alignment is done on relative addresses, so the size of the user block can affect the location of the data in the file. ./src/H5D.c ./src/dsets.c Added a test for, and fixed the data space caching bug in datasets. Extending a dataset through one handle will cause all other handles to the same dataset to get the new dataset size. ./src/H5S.c ./src/H5Sprivate.h Removed an unused argument from H5S_read() which duplicated information from the other argument. ./config/linux Made `--enable-parallel' the default on my system. It used to be that way before but then I accidently turned it off and forgot about it. ./src/H5Fmpio.c Qualified some function arguments with __unused__. Changed a couple places where NULL was returned on error for herr_t functions. ./src/H5P.c Removed unused autos from H5Pset_mpi().
* [svn-r411] Added data-transfer-mode to various function to specify whichAlbert Cheng1998-06-071-7/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mode to use for data transfer. Currently, INDEPENDENT transfer is the default mode. Collective is supported for files opened via the MPIO driver. Specific changes to individual files follow. H5D.c: Replaced previous kludge of passing xfer_mode via the file access_mode with xfer_mode function parameter all the way to the low level I/O drivers. H5Dprivate.h: The H5D_xfer_t.xfer_mode is now used in serial and parallel modes. Removed the "HAVE_PARALLEL" macro condition to support it. H5Dpublic.h: Added H5D_XFER_DFLT as a new value for H5D_transfer_t and removed the HAVE_PARALLEL condition macro to make the H5D_transfer_t definition available to both serial and parallel version. H5B.c: H5F.c: H5Farray.c: H5Fcore.c: H5Ffamily.c: H5Fistore.c: H5Flow.c: H5Fmpio.c: H5Fsec2.c: H5Fsplit.c: H5Fstdio.c: H5Gnode.c: H5HG.c: H5HL.c: H5O.c: H5Sprivate.h: H5Ssimp.c: debug.c: Added xfer_mode to the argument lists of the following routines to specify data transfer mode. Then updated calls to these routines with appropriate transfer mode. Whenever cases that collective mode is inappropriate (e.g. object header read-write, flush), H5D_XFER_DFLT is used. The H5D_XFER_DFLT mode is currently acting the same as the independent mode. H5F_block_read H5F_block_write H5F_arr_read H5F_arr_write H5F_core_read H5F_core_write H5F_fam_read H5F_fam_write H5F_mpio_read H5F_mpio_write H5F_low_write H5F_low_read H5F_sec2_read H5F_sec2_write H5F_split_read H5F_split_write H5F_stdio_read H5F_stdio_write H5S_simp_fgath H5S_simp_fscat H5S_simp_read H5S_simp_write H5Fprivate.h: H5P.c: Removed access_mode field from struct H5F_access_t type. The access-mode was the initial design to control independent or collective I/O mode. It is now supported by the data transfer mode.

Use it like this: HDfprintf(stderr,"size is %Zd\n", (size_t)x); ./src/H5AC.c ./src/H5F.c ./src/H5Fprivate.h The maximum number of meta data objects that can be cached can be set from the application (but the library might not honor it every time; it's a hint). ./src/H5D.c Changed a warning message so it's not so alarming. ./src/H5Fistore.c Chunks can be cached. ./src/H5O.c ./src/H5Oprivate.h Added H5O_copy() and H5O_free() to copy and free messages. ./src/H5P.c ./src/H5Ppublic.h Added H5Pset_cache() and H5Pget_cache() and changed lots of "template" to "property list". ./src/H5Z.c ./src/H5Zpublic.h Miscellaneous little things to clean up. Mostly just removed H5Z_MAXVAL and added H5Z_USERDEF_MIN and H5Z_USERDEF_MAX. ./MANIFEST ./test/Makefile.in ./test/chunk.c [NEW] Added a performance test for chunk caching. It looks at the amount of I/O instead of timing because timing is partly dependent on the chunk size and I wanted a measurement that was a function of only the cache size. Run `chunk' with no arguments and then say `gnuplot x-gnuplot' to see the plots (press return between plots). Postscript files are created for each plot. ./test/big.c ./test/cmpd_dset.c ./test/extend.c ./test/external.c ./test/gheap.c Added H5F_ACC_DEBUG so we can see cache performance statistics.

Added `z' to the debug list. ./src/H5B.c ./src/H5Bprivate.h ./src/H5Gnode.c ./src/debug.c Cleaned up some indentation and added support to print istore B-trees. From the debugger, give the B-tree address and the dimensionality from the layout message of the object header. ./src/h5ls.c The oid is printed as w:x:y:z where w and x are the file ID and y and z are the OID within the file. You can give z or y*2^32+z as an argument to the debugger to print the object header for the object. ./src/H5AC.c Cleaned up statistics and made them match those reported by H5T and H5Z. ./src/H5MM.c ./src/H5MMprivate.h ./src/H5Fistore.c Finally got rid of a couple of long-standing const cast warnings.

That's been fixed now. All dataset size calculations are done with `hsize_t' which is normally defined as `unsigned long long'. ./src/H5F.c ./src/H5Ffamily.c ./src/H5Fprivate.h ./src/H5P.c ./src/H5Ppublic.h The file family member size can now be set/queried. The default is still 64MB, but it can be set to 1GB by saying: H5Pset_family (plist, 30, H5P_DEFAULT); When opening an existing file family the specified bits-per-member is ignored and the first member of the family determines the bits-per-member, which can be retrieved with H5Pget_family(). ./acconfig.h ./configure.in ./src/H5config.h ./src/H5public.h Added `--disable-hsizet' so that those with old GCC compilers (<2.8.1) can still compile the code. ./src/H5.c ./src/H5private.h Added HDfprintf() which works just like fprintf() except you can give `H' as a size modifier for the integer conversions and supply an `hsize_t' or `hssize_t' argument without casting it. For instance: hsize_t npoints = H5Sget_npoints(space); HDfprintf(stdout,"Dataset has %Hd (%#018Hx) points\n", npoints, npoints); You can now give `%a' as a format to print an address, but all formating flags are ignored and it causes the return value of HDfprintf() to not include the characters in the address (but who uses the return value anyway :-). Example: H5G_t *grp; HDfprintf(stdout, "Group object header at %a\n", &(grp->ent.header)); Added HDstrtoll() which works exactly like [HD]strtol() except the result is an int64. ./src/debug.c Large addresses can now be entered from the command-line. Use either decimal, octal (leading `0') or hexadecimal (leading `0x') when giving the address. ./src/h5ls.c The printf format for dataset dimensions was changed to `%Hu' to support large datasets. ./test/big.c [NEW] A test for big datasets on 32-bit machines. This test is not run by default. Don't try to run it on an nfs-mounted file system or other file system that doesn't support holes because it creates two 32GB datasets of all zero.

This isn't fully tested yet, so hsize_t and hssize_t are defined as size_t and ssize_t in H5public.h. Setting them to larger values will trip up gcc versions less than 2.8.1 on x86 platforms. Documented unused function formals with `__unused__' before the formal name. This also has the effect of supressing warning messages for gcc since it's defined to be `__attribute__((unused))' in the H5private.h file. ./src/debug.c ./src/h5ls.c If the file name contains a `%' then the file is opened as a file family with H5P_DEFAULT for the file member access property list. ./src/h5ls.c The group name is optional, defaulting to `/'. ./src/hdf5.h Added some missing public header files.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./src/H5D.c Zero element requests for H5Dread() and H5Dwrite() succeed. ./src/H5F.c ./src/H5Fprivate.h All files will have a root group. This greatly simplifies the library at the expense of ~1k extra bytes in files that have only one object. ./src/H5D.c ./src/H5Dprivate.h ./html/Groups.html Functions that used to take a file ID and an object name can now take a group ID instead of a file ID. This doesn't change the API, only it's documentation. ./src/H5G.c ./src/H5Gprivate.h ./src/H5O.c ./src/H5Oprivate.h Removed extra file arguments from some internal functions since the file pointer can be found from the group pointer or a symbol table entry (ent->file or H5G_fileof(group)). Besides, when we eventually implement mounting one file on another, H5G_namei() might return a different file than what you gave it, and that file is part of the returned symbol table entry. ./src/H5G.c Fixed bug with `.' appearing in a name. It used to hang the library. ./src/Makefile.in ./src/h5ls.c [NEW] ./MANIFEST Added `h5ls' a simple program that takes a file name and a directory and lists the contents of that directory using H5Giterate(). ./test/istore.c Changed an argument to H5G_create(). ./test/tstab.c Removed test_1 which was testing that files with a single object don't have a root group. This no longer applies.

The user must have reserved enough space in the external file and the data space must allow an increase the the slowest varying dimension. See test_3() of ./test/external.c ./src/H5Oefl.c ./configure.in ./src/H5Fprivate.h Fixed an overflow bug with unlimited external storage. ./src/H5V.c Fixed a cast warning. ./test/dsets.c Make better use of automatic error reporting.

Besides, our test files only use them in a handful of places and it's probably useless to export them to the app. The app is always written in terms of standard numeric types or its own numeric types and probably never in terms of HDF5 numeric types. If it were, then the user would have to copy from their type to hdf5 type for almost every hdf5 API function call! Same goes for return values. I also removed SUCCEED/FAIL from the API since apps should be checking against zero anyway. if (FAIL==(space=H5Screate_simple(...))) /*wrong*/ if ((space=H5Fcreate_simple(...)<0)) /*right*/ ./src/H5.c Changed arguments of H5version() from `uintn' to `unsigned'. ./src/H5Tpublic.h ./src/H5T.c Changed return type of H5Tget_nmembers() from `intn' to `int' ./src/H5A.c ./src/H5Aprivate.h ./src/H5Apublic.h Changed `H5Asearch_func_t' to `H5A_search_func_t' and moved its definition from the public to the private header file. ./html/H5.format.html Documented changes made to the external file list (H5O_EFL) message. ./src/H5D.c ./src/H5Dprivate.h ./src/H5E.c ./src/H5Epublic.h ./src/H5O.c ./src/H5Oefl.c ./src/H5Oprivate.h ./src/H5P.c ./src/H5Ppublic.h Added partial support for external raw data files. HDF5 can now describe external raw data files by listing the file names, offsets, and size for a dataset. However, we will restrict a dataset to be stored "contiguously" when the external file list is viewed as a single address space. The current implementation is unable to read/write to external files--that will come later this week as will documentation. For now, take a look at ./test/external.c, particularly the calls to H5Pset_external(). ./test/Makefile.in ./test/external.c [NEW] ./MANIFEST Added tests for external storage. Note: the read test is supposed to fail at this point since reading external datasets is not implemented yet. There is no write test. ./src/H5S.c ./src/H5Sprivate.h ./src/H5Ssimp.c Added H5S_get_npoints_max() to return the maximum possible number of data points in a data space. Added an extra argument to H5S_get_dims() which returns the maximum dims. ./src/H5F.c ./src/H5Fprivate.h ./src/H5Fpublic.h ./src/H5M.c [DEPRICATED] ./src/H5Mpublic.h [DEPRICATED] Changed `template' to `property list' in lots of places. ./src/H5Osdspace.c Removed an extra `\n' from a print statement. ./src/H5S_public.h Changed H5S_UNLIMITED to the maximum size_t value. ./test/extend.c "Extendable" is spelled "extendible". ./src/H5Farray.c ./src/H5V.c ./src/H5Vprivate.h ./test/hyperslab.c Strides are now type ssize_t instead of int. These have nothing to do with the sample granularity arguments for hyperslabs, which are also called "strides" in the code. ./test/tstab.c Changed assumptions about default address and length sizes.

Fixed bugs in INT64DECODE() and UINT64DECODE() for big-endian architectures. This fixes all the bugs with the Irix -64 compile. ./src/H5F.c The default address and length sizes are set according to the sizeof(size_t) now that the bugs have been fixed. ./src/H5Fpublic.h Removed a trailing comma in an enumerated type. ./src/H5Fstdio.c ./src/H5Fsec2.c Added two more calls to fseek64() and lseek64(). Removed `long long' in place of `int64' to suppress -ansi warnings. ./src/H5P.c Replaced a FAIL with H5F_LOW_ERROR. ./src/H5private.h ./configure.in Increased version number to hdf5-1.0.1a since we've already released hdf5-1.0.0a. Include <sys/types.h>. Fixed indentation. Fixed detection of off64_t for old Irix systems where it might be a struct. ./src/Makefile.in Moved a comment from the shell to the makefile since some versions of sh barf on interactive comments. ./config/linux Allow overriding of the CC variable from the command-line. It still defaults to gcc but this allows us to specify a complete path from test scripts by saying: CC=/usr/local/tools/gnu/gcc sh configure

H5Fcreate() and H5Fopen() are more strict now about which flags are acceptable for the operation. ./src/H5Fprivate.h ./src/H5F.c ./src/H5C.c Changed the file access template to make it more general.

Kim or Albert: I notice in H5Cset_mpi() you copy the MPI communicator. Do you need to do something similar in H5C_copy()? ./src/H5F.c Added more error checking for the file creation and access property lists because it used to be possible to make the library dump core by swapping the creation and access property list ID numbers of H5Fcreate(). ./test/istore.c ./test/tfile.c ./test/th5p.c ./test/theap.c ./test/tohdr.c ./test/tstab.c ./testpar/testphdf5.c One must pass H5C_DEFAULT as the file creation or access property list in order to get the default property list.

The "5000 items in a group test" now takes 1.6 seconds. ./src/H5private.h Removed inclusion of mpi.h and mpio.h since they're included from H5public.h. ./src/H5Cpublic.h ./src/H5C.c Added H5Cset_stdio(), H5Cset_sec2(), H5Cset_core(), H5Cset_split(), and H5Cset_family() in addition to the H5Cset_mpio() that Kim and Albert already wrote. We still need the H5Cget_driver() and an H5Cget...() counterpart for each of those functions. The split and family drivers still need a little work but I'm checking this in anyway.

H5Fprivate.h: The hardcode setting to "define MPIO as the default IO when HAVE_PARALLEL is set" cause all test programs to fail since none of them is coded with the needed MPI_Initialize. Change it back to the previous setting of using sequential I/O allows user to use sequential I/O by default and use MPIO only if he/she explicitely asks for it via access template setting.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./Makefile.in Added more dependencies to .PHONY. ./src/H5D.c The write side of the I/O pipeline is implemented now too. Things are looking good for the prototype and it's just a matter of populating the library with the data type and data space conversion functions. ./src/H5Farray.c ./src/H5Fprivate.h ./test/istore.c Changed the order of the arguments for H5F_arr_read() and H5F_arr_write(). ./src/H5P.c ./src/H5Pprivate.h Changed the names of the arguments of H5P_find(). Fleshed out the mgath and fscat callback types. ./src/H5Psimp.c Added stubs for H5P_simp_mgath() and H5P_simp_fscat() that operate on the entire data space. Quincey, once you have the data space hyperslab stuff in place let me know and I'll finish the H5P_simp_*() functions to do partial I/O. Or you can take a look at it too if you like; there's some comments in there for you. ./src/H5V.c ./src/H5Vprivate.h Changed dimensionality arguments from `size_t' to `intn' to be consistent with the rest of the library and to get rid of warnings on 64-bit Irix.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ---------------------- ./html/Datasets.html Removed some archaic comments about data spaces. Fixed example code. ./MANIFEST ./html/H5.format.html ./src/H5O.c ./src/H5Oprivate.h ./src/H5Ocstore.c [DELETED] ./src/H5Oistore.c [DELETED] ./src/H5Olayout.c [NEW] ./src/Makefile.in ./test/istore.c Replaced H5O_CSTORE and H5O_ISTORE messages with a more general H5O_LAYOUT message. ./src/H5D.c ./src/H5Dprivate.h ./src/H5Dpublic.h A little more work on the pipeline. Access to the file data is through the new H5F_arr_read() and H5F_arr_write() which do I/O on hyperslabs of byte arrays and don't depend on data layout. This should simplify the I/O pipeline quite a bit. I also added another argument to H5Dread() and H5Dwrite() to describe the hyerslab of the file array on which I/O is occuring. We discussed this at last week's meeting. ./src/H5Farray.c [NEW] Added functions that sit on top of H5F_block_read() and H5F_istore_read() and implement a common set of functions between all layouts. This means I/O of hyperslabs of byte-arrays in the file to arrays of bytes in memory. When operating on arrays of elements (>1byte) then we just add another dimension. That is, a 10x20 array of int32 becomes a 10x20x4 array of bytes. [This is the area I'll be working on most of next week to implement partial I/O for contiguous data and to improve performance for chunked data.] ./src/H5Fistore.c ./src/H5Fprivate.h Replaced the H5F_istore_t data type with the layout message H5O_layout_t which looks almost the same. Eventually I'd like to rename `istore' to `chunked' everywhere and use `istore' for 1-d storage where the chunks are all different sizes like in the small object heap where each object is a chunk. ./src/H5V.c Changed ISTORE to LAYOUT in one place. ./test/dsets.c Fixed for extra argument to H5Dread() and H5Dwrite().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ./src/H5Cprivate.h Changed H5Csetparm() to H5Cset_prop() and changed it to pass property values by value instead of reference. Changed H5Cgetparm() to H5Cget_prop(). Changed data types of file creation properties so the application can use `int' or `size_t' for most properties. Properties and their types are documented in H5Cget_prop(). Changed H5C_class() to H5Cget_class() to make the naming more uniform across packages. ./src/H5Cpublic.h Changed names of properties to make them more uniform across packages: H5F_USERBLOCK_SIZE became H5F_SIZEOF_USERBLOCK, H5F_OFFSET_SIZE became H5F_SIZEOF_ADDR, H5F_LENGTH_SIZE became H5F_SIZEOF_SIZE. ./src/H5D.c ./src/H5Dprivate.h Added support for chunked data storage. There still isn't any support for data type conversion or data space conversion, so chunked storage doesn't do much at this time. ./src/H5E.c ./src/H5Epublic.h Added the H5E_TEMPLATE major error number. I'm about the change the HGOTO_ERROR() and HRETURN_ERROR() macros to take an error string as an additional argument instead of specifying it as a comment. ./src/H5Fistore.c Added `const' to the `buf' argument of H5F_istore_write() although this temporarily causes a compiler warning. ./src/H5Fprivate.h Changed data types of certain file-related variables from types like `uint8' to `uintn' since the library data types should not depend on the file data types. ./src/H5P.c ./src/H5Pprivate.h ./src/H5Ppublic.h Moved H5Pget_lrank() to H5Pget_ndims(), and H5Pget_ldims() to H5Pget_dims() to make naming more uniform. Dimensions should always be of type `size_t'. Similarly for H5P_get_lrank() and H5P_get_ldims().
